silicon anode battery April 22, 2023, 07:56:15 pm I tend not to post or share about new battery tech 'cause there is so much smoke and mirror hype. But I thought you folks might be interested in what's coming down the road. At the moment we are using lithium-ion batteries with carbon-based anodes. This new battery tech is that lithium-ion batteries use silicon-based anodes. This new tech makes very large leaps in just about all measures. And reduces the weight to about a tenth. Our car and rv batteries could almost become standard flashlight size. 100% Silicon Nanowire Batteries from Amprius Technologyglen 2 Likes
Re: silicon anode battery Reply #1 – April 23, 2023, 02:58:37 pm Battery technology is moving forward at a rapid pace.The problem that all the green and climate change people fail to see is just howmuch mining it takes to make happen.Mining is a horrible business for the environment, but a necessary one to keepthis world going. Stripping the earth for rare earth minerals is some of the worst too.

Re: silicon anode battery Reply #3 – April 24, 2023, 09:58:32 am Well, sand is not a very limited resource. I'm thinking folks can find it in just about any country.glenps - What we, all the folks in the world, should be more concerned with is phosphate. Spoiler alert - One country in the world has 70% of the reserves. All the rest fall to very low numbers - 2% or less per country.

Re: silicon anode battery Reply #5 – April 28, 2023, 11:56:51 am I'd like to make a suggestion: the phrase "green and climate change people" has, unfortunately, political connotations, and politics are out of bounds here. It would have been better (and probably quite accurate) to simply say that "what people fail to see is how much mining it takes." Leave out the adjectives, in other words, and Jota's point still comes across: electric vehicles, and the battery technology they depend upon, are not free of environmental consequences. Nor, as Larry Wade and others have pointed out, is the electricity to power all those Teslas and other vehicles free of pollution at the generating plant, coal mine, oil well, etc. Likewise, producing solar panels is a polluting business. No source of energy is really clean. We just need to look at all the factors when considering what's best. 7 Likes
Re: silicon anode battery Reply #6 – April 28, 2023, 12:44:41 pm Piggybacking off of Andy’s post, another overlooked (IMO) issue is the impact of dealing with lithium battery fires. They are a special breed and many of our first responders are not well equipped or trained to deal these types of fires:First responders sound alarm over EV batteries after electric F-150s burst... 1 Likes
Re: silicon anode battery Reply #7 – April 28, 2023, 01:21:21 pm Fortunately concerning motorhomes and house batteries, Lithium batteries are usually the less flammable versions, Lithium Iron Phosphate. Heavier and not as compact (energy dense) the tradeoffs for being less likely to catch fire are worth it. In electric vehicles, like cell phones, the push is for lightness, density and fast charging. Temperature management is more difficult in moving vehicles. In my motorhome, actual high drain usage is confined to short periods. Charging by solar is pretty slow, and the environment is not as harsh both with temperature and vibration. The emphasis is on long duration, normally low usage. While it seems that many electric vehicles are catching fire, plenty of gasoline powered cars (fewer diesel) catch fire daily. Water usually suffices to put out those fires. Lithium just reacts worse with water. RonB 1 Likes
